U don't have to be pretty to be a bright beautiful person. It doesn't matter what other people think, as long as you believe and are confident in your self, you can be a positive happy person. You are amazing.
So true, it can be hard to understand sometimes until you have experienced ups and downs including getting back up. It is easy to not clearly appreciate or clearly at the moment understand the significance of little things but in time they add up and you will later learn a lot and remember a lot from those experiences!! Enjoy each day, each person in your life and new people you meet!
